VARITECTOR SPC

The VARITECTOR SPC is characterised by highest protective functions with compact dimensions. The arrestor of the modules can be removed or exchanged during running operation impedance-neutral – without interrupting the measuring circuit. Thus, the product is ideally suited for protecting instrumentation, control and automation circuits.

With the VARITECTOR SPC R modules, error detection and error messages are realized by internal monitoring. The green LED indicates the active protective function. The red LED indicates a fault condition. This information is transmitted to the optional V-Control evaluation unit. From there, the information can be signalled at e.g. a controller.

Maintenance intervals are simplified by the V-TEST test unit, which is used for testing the function of the VARITECTOR SPC. This test method satisfies the requirements of standard IEC62305.

Due to the impedance-neutral removing of the arrestor, the VARITECTOR SPC modules can be used instead of terminals. Because in process, industry and building automation, every millimetre of width in the switching cabinet counts. For four binary signals or two analogue signals, just 17.8 mm of space are used. By simply snapping onto a grounded mounting rail, time savings are also ensured when connecting. A colour code identifies the various voltage levels for all VARITECTOR SPC modules. This simplifies maintenance work during operation. The EMC set offers additional convenience for connecting shielded cables.

Your benefits:

• Monitoring function
  Status display and message function:
  the protective function can be evaluated externally.

• Testable
  The pluggable arrestor can be tested with V-TEST instrument in accordance with IEC62305. Also suitable for PU I and PU II modules.

• Convenient and safe
  Misconnection of the modules is prevented by a coding element.

• Large variety
  A solution for every type of surge protection:
  current loops and binary signals as well as integrated components and combinations of current loops and voltage supply e.g. 24 V.

• Standard-conformant
  Usable in accordance with installations standard IEC 62305:
  safely discharges high impulse currents up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) to PE. Tested for class D1, C1 and C2 to IEC 61643-21.

• Space-saving
  Saves space in the switching cabinet:
  4 binary signals or 2 analogue signals on 17.8 mm.

• Quick identification 
  Color-coded marking:
  simple identification of the different voltage levels in the switching cabinet.
